Chapter 5. Configuring Red Hat Cluster With system-config-cluster
Note
Circumstances that require enabling Run Exclusive are rare. Enabling Run
Exclusive can render a service offline if the node it is running on fails and no other
nodes are empty.
7. Select a recovery policy to specify how the resource manager should recover from a service
failure. At the upper right of the Service Management dialog box, there are three Recovery
Policy options available:
• Restart — Restart the service in the node the service is currently located. The default setting is
Restart. If the service cannot be restarted in the current node, the service is relocated.
• Relocate — Relocate the service before restarting. Do not restart the node where the service is
currently located.
• Disable — Do not restart the service at all.
8. Click the Add a Shared Resource to this service button and choose the a resource listed that
you have configured in
Note
If you are adding a Samba-service resource, connect a Samba-service resource
directly to the service, not to a resource within a service. That is, at the Service
Management dialog box, use either Create a new resource for this service or Add
a Shared Resource to this service; do not use Attach a new Private Resource to
the Selection or Attach a Shared Resource to the selection.
9. If needed, you may also create a private resource that you can create that becomes a subordinate
resource by clicking on the Attach a new Private Resource to the Selection button. The process
is the same as creating a shared resource described in
The private resource will appear as a child to the shared resource to which you associated with
the shared resource. Click the triangle icon next to the shared resource to display any private
resources associated.
10. When finished, click OK.
11. Choose File => Save to save the changes to the cluster configuration.
Note
To verify the existence of the IP service resource used in a cluster service, you must use
the /sbin/ip addr list command on a cluster node. The following output shows the
/sbin/ip addr list command executed on a node running a cluster service:
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
